CTICasesDabbing-Associated Acute Lung Injury
Imaging findings
Chest radiographs and chest CT demonstrate multifocal, multi-lobar consolidative opacities in both central and peripheral regions, in a young intubated patient with acute lung injury. The patient had a history of daily dabbing of marijuana concentrates (butane hash oil) for several months.
Key takeaways
Dabbing involves inhaling vaporized highly concentrated tetrahydrocannabinol (THC) extracted using solvents like butane. It is associated with acute lung injury (chemical pneumonitis) which can radiographically and clinically mimic E-Cigarette or Vaping Product Use-Associated Lung Injury (EVALI). Clinicians must obtain a detailed exposure history, specifically asking about dabbing, when vaping-associated lung injury is suspected.
